Frank Zappa was an innovative composer and righteously outspoken defendant of freedom of speech. But did you know he was also stone cold sober?

Believe it or not, the Mothers of Invention leader, Captain Beefheart cohort, and psychedelic rock Übermensch recorded tunes like "Muffin Man" and albums like Lumpy Gravy without imbibing a single mind-altering substance.

We can't help but wonder: When Dweezil Zappa brings his All Zappa Revue, Zappa Plays Zappa to the Culture Room on February 2, will he uphold his father's abstinence?

Doesn't, like, everybody smoke weed at this point? Plus, Dweezil has spent way too much time in the post-Phish jambake circuit to have not huffed a children party's worth of balloons filled with nitrous oxide.

In 2011, Dweezil was interviewed by Spinner and revealed that, up to that point, he had still had never gotten drunk or smoked, in his life. But a lot can change in two years. And come February 2, we plan on cornering Dweezil Zappa and forcing him to take a urine screen. We need answers, dammit!
